AAn-object of this invention is to providea valve and valve seat neither of which is exposed to the 'abrasive force of fluid.

A further object is to` provide mechanism wherein nearly all of the wear is upon minor parts which may be replaced at minimum cost.

In carrying out the simplest formof this invention, I employ a valve andv valve seat, and upon the valve member above the valveI attach Y a tubular portion having a close sliding t within an opening above'the valve seat and having an inlet proximately above the valve and an outlet discharging into a chamber at the upper end of which is anopening Within which a solid vexabove the valve has a close sliding t. Y i Y f In another form of the invention I employ all the elements of the iirstform and add a second tubular portion to protect the discharge opening in the female member from the abrasiversec-V In other forms of the invention IV provide that the parts subject to most wear may be replaced. The particular construction ofthis valve fand the several modifications thereof'will more clearly appear from the accompanying drawings and" speciiication which follow.

through a passage. yIn the Vdrawings the part'3 may designate the. wall of a chamberv or a plug to be pressed into or otherwise tightly secured within a pipeline or at either end of a pipe. Said shell has an opening 3d within which valve head la has a close Working fit and has anothervopen` f ingA 3c Vof restricted diameter which opening af-y vfords Va closeworking iit over` the tubular portion If. At the lower end of shell 3 a seat 3b is provided vto engage valve surface le. Intermediate of restricted openings 3c and3d is positioned an ellipsoidal opening/3a of enlarged diameter.

lValve l. may be threadedlyconnected to-shaft 'extension '2aV of shaft 2. Said valve includesan f outwardly inclined shoulder le to engage the tais an axial passage ld which opens at one end.

pered seat 3b anda headY I a which is cylindrical in shape, except for the tapered end which works -in passage 3d of the shell. Between the two ends through diametrical port tothe chamber 3a. The other end of passageld has a port through opening Ic to the outside. In the open position of Y the, valve as shown, in Fig.r1 fluid maypass either direction throughthe valve. The flow may enter through funnel shaped opening 3e in the shell, pass through'opening r3a, ports lb, passage Fig. 13 is a view partly in elevation and partly /CO I d, and go out throughports'lc; o/r the now/may go in the opposite direction as is apparent. Whichever route the flow may take valve seat 3b is far removed from the path of flow and the seat will, therefore, not be damaged by abrasive substances in the fluid that passes through. Valve surface Ie is likewise away from theflow path by the length of `straight section Ih. Valve seat 3b and valve surface le remain away from the flow path as long as the valve remains open as will appear in Fig. 2, which shows the valve closing.

` head Ia has continued to engage deeper into opening 3d after and from the time when the closing position has reached the stage shown in Fig. 2. It is, therefore, apparent that as the surface Ie approaches seat 3b the passage of fluid l l between these surfaces is -rst cut off by head Ia entering passage 3d, and Alater this cut off is made more leak proof by the straight section Ih entering the passage 3c. The portion If acts as a shield to protect the valve and valve seat by diverting the ow away from them through the opening Id which is streamlined to afford an'easy flow path. Fig. 4 shows the ports Ib and Ie turned axially 90 from the position shown in Figs. 1, 2 and 3.

As stated, it is immaterial whether the direction of ow is one way or the other. It should also be observed that the same valve action will result'whether the moving part be the valve I or the shell 3.

' Means for actuating the movable part may be of any desired form depending upon the character of the installation and as this construction forms no part of `the present invention,`it is 'not shown. Such means of housing and operating the valve are, therefore omitted.

Figs. 5, 6 and 7 illustrating a modification of the valve assembly shown in Figs. 1,2 and 3, show that an upper sleeve may be provided above valve head IAa of valve IA with ow passage IAd through portion IAf which passage will re. lieve passage 3d from some of the abrasive action of the fluid, the port IAb' being provided tov admit or discharge (depending upon -the direction of flow) the fluid going into or passing out of passage IAd The position of valve IA at the time fluid flow is rst stopped is shown in Fig. 6. Fig. 'I showing the completely closed position of the valve, may be compared With Fig. 3 to note that the action of valve head IAa is the'same as that of the similar part Ia in Fig. 3.V

It will be noted that horizontal port IAb, lower horizontal port IAc, lower vertical passage IAd, valve surface lAe, lower tubular portion IAf, and

straight section Iah correspond in construction l ing a funnel shaped end 4e corresponding to the;V

similar portion 3e in Fig. 1 and a central opening 4d to closely receive the valve head IBa. This sleeve having threaded engagementinto the'upper end of shell 3A, may be used so that these ICd.

parts which stand most of the wear may be quickly and cheaply replaced. Valve body IB. upper horizontal port IBb, lower horizontal port IBC, vertical passage IBd, valve passage IBe,`

tubular portion IBf, and straight section IBh correspond in constructionandlpurpose to the similar portions 'bearing the same numbers without subscripts in Figs. 1, 2, 3, and 4.

The ellipsoidal opening 3Aa, valve seat 3Ab. lower restricted opening 3Ac, and outer surface 3Af in-Figs. Sand 10 are the same in use and purpose as the similar portions referred to by the same characters'less the letter A in Figs. l, 2, 3,

Fig. 10 shows that valve head ICa may be slipped over internally threaded upper extension ICg and locked in place by threaded engagement with lower extension ICg of the' part IC'. In this construction upper sleeve member IC' diverts the path of flow through opening Parts ICa, IC', and sleeve 4 which withstand most of the abrasion provide, as in Fig. 9, that the most usual replacements may be quickly and cheaply made. Valve body IC, intermediate horizontal ports ICb, upper horizontal passages ICb, lower horizontal port ICC, lower vertical passage ICd, valve surface ICe, lower tubular portion ICf, upper tubularA portion ICf, and straight section 'ICh correspond in use and purpose to the similar portions referred to in Figs. 5, 6 and 7 by the same characters except that the letter A in Figs. 5, 6 and 7 is changed to C in l Fig. 10.

. The invention as herein illustrated and described is .manifestlly subject 4to such changes in construction and arrangement of parts as will be within the scope and purpose of thevstated objects and appended claims.
